Description
Technical Field
The invention relates to the technical field of intelligent substations, in particular to a substation secondary circuit reconstruction and expansion method.
Background
Currently, intelligent substations have entered the comprehensive construction application phase. By the end of 2016, 3000 seats of a newly built intelligent substation for production are built, and a perfect technical system and a series of technical standards of the intelligent substation are formed. The method has the advantages that important results are achieved in theoretical research, technical research and development, key equipment development, test system, standard formulation and engineering application, the safety, controllability, adaptability and interactivity of the transformer substation are remarkably improved, the construction efficiency is improved, and the transformation of the power grid development mode is promoted.
In this process, since the intelligent substation widely adopts the IEC61850 communication technology, compared with the conventional substation, its structure and morphology are revolutionarily changed, and the SCD file (Substation Configuration Description, total station system configuration file) is used as a substation configuration file capable of reflecting the configuration information of the intelligent substation system, and describes the example configuration and communication parameters of all intelligent electronic devices IEDs (Intelligent Electronic Devices ) in the substation, the communication configuration among IEDs, and the information of the primary system structure of the substation. Common causes of problems in SCD files during debugging are: secondary circuit design change, ICD file (IED Capability Description, IED capability description file) change, GOOSE layer parameter name and remote signaling name modification errors and the like, and the prominent problem faced by reconstruction and expansion is how to develop secondary virtual circuit design work based on the latest version of SCD file.
At present, the design of a process layer virtual loop is mainly carried in an Excel form mode, and an integrator completes the configuration of the process layer loop in a configuration tool according to the Excel form in the process of integrating SCD and integrates an SCD file. If the virtual loop changes in the process, the integrating manufacturer can revise the SCD file after the design is changed. After the engineering is put into operation, the virtual circuit in the SCD file is the latest version of the virtual circuit consistent with the site.
As intelligent substations are put into operation in large numbers, there is an increasing need for rebuilding and expanding intelligent stations. The new construction and the rebuilding of the intelligent substation are usually carried out in secondary design by different design units, and the design result of the virtual secondary circuit can not be well continued from the new construction stage to the rebuilding stage, so that the design can only be carried out aiming at the newly increased interval during the rebuilding design, and the integral influence is difficult to grasp. In the reconstruction and expansion construction process, due to lack of design change details, a construction unit cannot reasonably evaluate the influence range of reconstruction contents. In order to avoid the risks accompanying reconstruction and expansion, construction and debugging are generally performed by adopting a mode of complete shutdown of the transformer substation, which is not properly implemented or even feasible in a central transformer substation or an important load transformer substation. Compared with the traditional transformer substation, the relay protection secondary circuit is converted into invisible virtual circuit network information from visual secondary wiring, and the problems of reconstruction and extension caused by the intellectualization and informatization of the transformer substation have to be faced.
However, the whole design process can refer to similar engineering, but the overall multiplexing degree and the extension degree are low, most of the work is either redesigned or full-disc copying and then refinement modification work are performed, and the real reconstruction extension continuity is not achieved.

Specifically, as shown in fig. 3 (a), the device information of the substation IED device obtained by analysis, for example, short names, device types, device manufacturers, models, software versions, and ICD files in a device list corresponding to 35KV (69) intervals, may be displayed in a layered display manner; further, as shown in fig. 3 (b), the virtual secondary circuit information of each IED device may be displayed in a classification display manner through GOOSE input, GOOSE output, SV input, and SV output, and specifically each virtual terminal description, virtual terminal application, direction, opposite side device name, opposite side virtual terminal description, and opposite side virtual terminal application is displayed, so that opposite side information in signal connection with the IED device can be intuitively displayed.
Further, the visual list obtained through the node information and the combination attribute of the substation IED equipment can be a visual edit list shown in fig. 4, namely a virtual secondary circuit connection list of the substation IED equipment, so that the connected signals and unconnected signals of the substation IED equipment can be intuitively and clearly seen, circuit design can be performed on the basis of the visual edit list, for example, operations of adding, deleting and modifying can be performed on the basis of the visual edit list, and network and point-to-point communication modes can be marked.
Further, after the secondary circuit of the transformer substation is reconstructed and expanded, information of newly-added equipment and circuits or deleted equipment and circuits is recorded in a classification display list of the virtual secondary circuit, for example, as shown in fig. 5 (a), after the A-phase circuit breaker, the B-phase circuit breaker and the C-phase circuit breaker are newly-added, the information of the newly-added equipment and the circuits is recorded in the classification display list of the virtual secondary circuit; similarly, for example, as shown in fig. 5 (b), after the automatic switching-on of the goose input-backup and the switching-on of the goose input-remote control 1 are deleted, the deletion equipment and the loop information are recorded in the classification display list of the virtual secondary loop, so that after the secondary loop of the transformer substation is reconstructed and expanded, the change part can be visually displayed, and the design inspection and construction efficiency can be improved.
